Yeah, I'd have to second that, SuperThrive isn't dangerous even in large amounts. Shouldn't do any harm at all.
MegaOctane12 Reviewed by MegaOctane12 on . Mixing Nutrients and Micro Nutrients? Is SuperThrive a Micro nutrient? Or is it just vitimins? I ask this because I want to know If Its ok for me to be mixing my water with Nutrients and Superthrive then letting it sit untill I need to refill again? About a week. I understand you should not mix Nutrients and Micro Nutrients Toegether. Untill you are going to be feeding them to the plants. Just wanna double check that its safe for these elements (Nutrients and Superthrive) to sit in the jug together untill its all used Rating: 5
